Little is known about the causes of enteric fever in Asia. Most cases are believed to be caused by Salmonella enterica serovar Typhi and the remainder by S. Paratyphi A. We compared their incidences… (More)

Epidemiology of rotavirus diarrhea in Egyptian children and implications for disease control.

Abdollah B Naficy, Remon Abu-Elyazeed, +9 authors JohnD. Clemens
American journal of epidemiology
1999

Reliable epidemiologic data are essential for formulating effective policy to control rotavirus disease through immunization. The objective of this study was to describe the epidemiology of rotavirus… (More)

Cholera outbreaks caused by an altered Vibrio cholerae O1 El Tor biotype strain producing classical cholera toxin B in Vietnam in 2007 to 2008.

Binh Minh Nguyen, Je Hee Lee, +11 authors Dong Wook Kim
Journal of clinical microbiology
2009

Vibrio cholerae O1 isolates collected during cholera outbreaks occurring from late 2007 to early 2008 in northern Vietnam were revealed to represent an altered strain containing the RS1 element… (More)

Cross-protection by B subunit-whole cell cholera vaccine against diarrhea associated with heat-labile toxin-producing enterotoxigenic Escherichia coli: results of a large-scale field trial.

JohnD. Clemens, David A Sack, +7 authors M Wasiqur Rahman Khan
The Journal of infectious diseases
1988

The B subunit (BS) of cholera toxin and that of the heat-labile enterotoxin (LT) of enterotoxigenic Escherichia coli (ETEC) are antigenically similar. We therefore assessed whether a combined cholera… (More)

Phenotypic profiles of enterotoxigenic Escherichia coli associated with early childhood diarrhea in rural Egypt.

Hind I Shaheen, Sami B Khalil, +10 authors Stephen J. Savarino
Journal of clinical microbiology
2004

Enterotoxigenic Escherichia coli (ETEC) causes substantial diarrheal morbidity and mortality in young children in countries with limited resources. We determined the phenotypic profiles of 915 ETEC… (More)

Malla Raghav Rao, Abdollah B Naficy, +6 authors JohnD. Clemens
American journal of epidemiology
2001

Campylobacter infection in developing countries has not received much public health attention because of the observation that infections are not associated with disease beyond the first 6 months of… (More)

Trend and disease burden of bacillary dysentery in China (1991-2000).

X Wang, Fang-biao Tao, +18 authors JohnD. Clemens
Bulletin of the World Health Organization
2006

OBJECTIVE We aimed to determine the burden of bacillary dysentery in China, its cross-regional variations, trends in morbidity and mortality, the causative bacterial species and antimicrobial… (More)
